In Vivo Capsule Image Bookmarking and Thumbnail Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Diagnostic imaging systems, such as capsule camera systems, generate large amounts of image data during procedures, making it time-consuming for medical professionals to navigate and identify relevant images within the vast datasets.
Innovation Solution
A method and system for displaying image sequences captured by in vivo imaging devices, which includes bookmarking images with associated annotation information and displaying thumbnail images alongside the main image sequence, allowing for quick navigation and identification of key frames using a timeline and user interface controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image data is displayed continuously at high frame rate, then diagnostic completeness is improved, but review time increases significantly
Solution Approach 1:
The patent segments the continuous image sequence into discrete bookmarked images and thumbnail representations. Instead of reviewing all frames continuously, the system identifies and marks specific diagnostically relevant images as bookmarks, allowing reviewers to jump directly to these segmented points of interest while maintaining diagnostic completeness.
Solution Approach 2:
The patent creates thumbnail copies of bookmarked images that can be displayed in a condensed format alongside or instead of the full-resolution image sequence. These thumbnail copies serve as visual markers that allow rapid navigation through the dataset without requiring review of every frame at full resolution.
2Ease of operation
If all image data is displayed simultaneously, then navigation to key frames is improved, but display complexity increases
Solution Approach 1:
The patent adds a temporal dimension to the display by showing thumbnails representing different points in the image sequence. Instead of displaying all images in a single spatial plane, the system uses a timeline-based approach where thumbnails are arranged chronologically, allowing navigation through time without increasing spatial complexity.
Solution Approach 2:
The patent introduces thumbnail images as an intermediary representation between the full image sequence and the user. These thumbnails act as mediators that provide visual cues about key frames without requiring the user to directly interact with or analyze every full-resolution image, simplifying the navigation interface.
Data Source
AI summary
A method and system for displaying images captured by an in vivo imaging device are disclosed. Embodiments according to the present invention display image sequence data in a first display area. When a first bookmarked image with annotation information is displayed in the first display area, a first thumbnail image in a second display area corresponding to the first bookmarked image is replaced to indicate an occurring correspondence between the first bookmarked image and the first thumbnail image corresponding to the first bookmarked image being displayed. In one embodiment, the method further comprises displaying the first thumbnail image in the second display area when one other image of the image sequence data is displayed in the first display area after the first bookmarked image is displayed.
